## Reflection: Real World Applications Job Offers and Cell Phone Plans: Making Informed Decisions with Mathematics - Section 1: Entry Ticket: Which Company to Work for?

I open this lesson on modeling real life scenarios using systems with a real world application around analyzing two job offers. The attached example of student work lends itself a conversation around applying previously learned concepts as well as applying the skill of justification in work.

I appreciate how this student showed understanding of how to interpret and apply function notation in this problem. The student also answers the last question and does provide a reasonable justification for choosing one job offer over the other. This is a good example of a student who is making progress around using evidence to justify their reasoning, but also is an area to continue to improve upon.
